  • A good driver for LED 3W

    posted by evgenic

    I bought this driver for 3W Osram LEDs (SKU194296). With this driver - good brightness LEDs, although it is not the limit, because the LED's operating voltage of 3.9 V and operating current of 750 mA. The driver outputs a voltage 3.63 V and current 650mA. Thus the total power is obtained understated ... But I tried to connect the LED Cree Q3.Operating current 700mA turned to him and he shines much brighter (a feature of the LED Q3). The advantages of this driver could be considered that it is made in the closed case and sufficiently thick wire.
    I would recommend using this driver with LED Q3.Power same but higher brightness.
    All in all - a good driver for LED 3W (2.5W ~ real power is ~2.5W , but the LED is less heated). I found this driver only on the DX (for the presence of rare items - I love DX). I recommend to buy!
  • This driver is not 680mA

    posted by whorled

    It is relatively inexpensive.It is small and light.It is waterproof.The wiring not too thin.It comes with a connector on the dc side.
    The DX listing for this product shows "Waterproof 680mA 3W Power Constant Current Source LED Driver ".The label on the driver has no output current shown, only "Output 1x3w"
    Came here expecting this driver to be suitable for power testing single 3w leds at 680mA. The driver only delivered 540mA into a single 3w led. It was tested with several different single leds: 2.5v red 660nm 3w leds, 3.5v blue 450nm 3w leds, and 3.7v warm white 3w leds. Multimeter showed each one receiving only 540mA.Left disappointed.
  • cheap, easy to install and good finished

    good product, looks very solid, is very nice finished and so easy to install.
    This is the best "partner" for a stream of leds... I used this and leds lights to iluminate my kitchen and looks great!. I installed this under the kitchen´s forniture to iluminate only part of the room and save some money.
    very good and cheap buy! probably I´ll buy more of this on my nexts home projects.

    * Very compcact * good build quality * easy to improve
    This driver is build on MC34063a base, so you can easily midfiy it, if you want to make dimminel light. All that you need to do, it's deolider 220 Ohm SMD resistor form the top of the board, and solider on ti's place in series 220 Ohm resistor and 5 KOhm potenciometr, and you get 3W led driver with variable current. But, if You ar intersted in usingi it on the lowest current you wil need to change Coil with bigger one, to prevent blinking
    Very good LED driverMust have for DIY projectVery cheap, about $1 per driver
